oonstmotion and arrangement of ports as Al horoimiftor described and particularly reoitol if: the claims.

In carrying out my invention I employ the usual headlights 5 and 6 controlled by the usual main switch '1. I also ompfioy safety lamp 8, located benooth'tlio rightliami tha WflJfQl mud g 'xzm'ai. In the lino loetwoen tho switch 3 211% the imaollights l locate an {HEX- ilizm'y a, Fitoh comprising suitable casing 9 gio'violod with faoo plate 16 by which i 46 may lm secured in place and onclosing' it shall 11 in which is mounted an insulating block 2 fiaiflfyl contacts 13, 1% and Above the cont a M16. adapted to engage more with pix mounted in a push button.

W wliicii foz'oecl outward 037 a spring 18 and omot tlescription of the some,

. vent-ion consists in the preferably mounted onJo guide rod 19, and

provided with a stop pin 20 by which it is prevontod from boing fOICEfl through the face pinto. The pooh button is also provided with a notch 21 which will engage with the face plate and 10* the pin in its closed position. The wire 2 from tho main switch leads to the contact 14: and from the contact 13 a wire 23 leads to the headlights,

while the contact 1-5 is connected by a wire 5:34; with the safety lamp.

This closes the cirwit to the safety lamp 8 which will be brightly lighted While the circuit to the headlights is through tho resistance coil 25 thus dimming the hoadiights 5 and 6. The safety lamp-being protected by the mud guard, will throw its rays forward; and light tho right lmnd side of the road so that the driver oan'ploinly see on obstructions in his path. Aftor the vehio 6 has passedthe push button is reloaseil, moving outward by its spring 18 and breaking; the circuit to the safety lamp 8, at the some time comleotin v tho. contacts and M so that tho hoa ligihts will again be brilliantly lighted.
